PET/CT

The Sovereign Health Imaging uses the most advanced PET/CT technology available. What does the our Biograph-64 PET/CT offer compared to other PET/CT systems?

  • The highest resolution in the market: 4 mm compared to 5-7 mm in other systems. PET resolution is measured in volumes; 3 therefore, a gain from 5 mm to 4 mm (4x4x4=64 mm with 3 5x5x5=125 mm ), doubles the resolution and improves image quality.
  • The fastest technology available: LSO detectors and Pico technology allow for faster scanning time and lower doses of radiopharmaceuticals. Scans can be performed in as fast as 6 minutes.

What is PET/CT?

The biograph PET/CT is a diagnostic imaging system that combines PET and CT into one unit. PET (Positron Emission Tomography) utilizes a low-level radiopharmaceutical to visualize processes or functions within the body. CT stands for Computed Tomography or CAT Scan. This technique uses x-rays to make cross-sectional images (called slices) of your body. The structure of body organs is more clearly visualized than with conventional x-rays.

Advanced system software in the biograph PET/CT combines the anatomical information obtained from CT with the functional PET information to form not a photograph, but a biograph - an image that records living tissues and life processes with great precision and detail.

Applications of PET/CT in Oncology

Metabolic imaging using F-18 Fluorodeoxyglucose (FDG) and PET/CT has become the cornerstone of oncologic imaging and has been shown to be useful in tumor staging and follow-up. PET/CT has also proven useful in predicting prognosis and treatment response. In certain diseases, such as lymphoma, higher FDG uptake is an indication of a higher grade malignancy.

Indications:

  • Differentiation of benign from malignant lesions.
  • Staging of malignant disease.

Evaluating chemotherapy response:

  • Early: after one or two cycles of chemotherapy.
  • Late: 3-4 weeks after completion of chemotherapy or 2-3 months following completion of radiotherapy.
  • Differentiation of local recurrence from post-surgical or post treatment
    changes.
  • Detection of early recurrence or metastasis through timely follow-up testing.

Applications on PET/CT in Cardiology

When compared to conventional SPECT imaging, PET/CT coupled with a 64-slice CT scanner is a faster, easier, and more accurate method to measure myocardial blood flow. Cardiac imaging with a 64 slice PET/CT has several advantages:

  • Faster acquisition times and the use of CT for attenuation correction eliminates frequently seen artifacts on conventional SPECT imaging in patients with a large body habitus.
  • The entire length of the study for both stress and rest imaging is less than 30 minutes.
  • Myocardial blood flow and reserve measurements allow the detection of small vessel or balanced three vessels disease. These patients will have normal SPECT studies.
  • The 64-slice CT allows for coronary artery calcium scoring which gives additional information about the severity of the coronary artery disease and can be an important factor for deciding the best treatment for the patient.
  • The combined PET multi-detector CT system allows for direct comparison of a PET study with CT coronary angiography performed in the same sitting. In combination, these two studies have been shown to have a negative predictive value of nearly 100% and can help avoid unnecessary catheterizations in normal patients.

Applications of PET/CT in Neurology

Indications:

  • Dementia: Differentiation of Alzheimer's disease from other types of dementia in its early stages.
  • Epilepsy: Localization of epileptogenic foci.

For these studies, we have acquired a quantitative program to compare patient studies with a normal brain database resulting in increased sensitivity and specificity.

CT Scanner While the medical literature shows that PET has utility in the evaluation of the following diseases, they are not currently approved by CMS. They may be pre-approved by some insurance carriers after justification is provided for the study.
  • Granulomatous Diseases and Sarcoidosis.
  • Chronic osteomyelitis.
  • Differentiation of loosening from infection in the evaluation of orthopedic hardware.
  • Localization of sites of infection in patients with fever of unknown origin.
  • Carcinoma of unknown primary.



Frequently Asked Questions

What is PET/CT used to examine?

The Biograph PET/CT can be used for a number of diagnostic reasons. The most common of which is in the imaging of neoplasms in the body. By showing not only anatomy, but function too, it is a powerful tool to help in the oncology arena.

Cardiac imaging is also part of PET/CT exams. It can show, not only if there is a blockage in a coronary artery, but also if the heart muscle is still functioning beyond the blockage. The last large segment of PET/CT exams focus on Neurology disorders, including Alzheimer’s and dementia imaging.

What preparations are necessary?

Some Biograph PET/CT scans require no preparation at all, while others might require you to modify your food, fluid, or medication intake prior to the scan. The scheduling Specialist or Technologist who helps you, will let you know specifically what to do before and after your scan. If possible, try to wear loose-fitting clothes on the day of your scan, and avoid caffeine so you won’t be restless. During the scan, all you have to do is relax, and lie as still as you can. You will first receive a small injection of a radiopharmaceutical contrast about 60 minutes before the actual scan. It will not make you feel any different. Depending on the type of study, you may also receive a contrast medium at the time of the CT portion. This is a dye that increases the quality of the CT images. The contrast medium may be administered orally, or by injection, or both. Some patients report a warm feeling or an unusual taste in their mouth from the contrast medium.

Should I tell the technologist about my medical history?

Yes. Before you are given a radiopharmaceutical or a contrast medium, be sure to tell the technologist if you have allergies, asthma, heart problems, diabetes and kidney problems; if you think you might be pregnant; or if you are currently undergoing any radiation therapy.

How long does the scan take?

The entire biograph PET/CT examination is generally performed in less than one hour, usually in about 40 minutes, providing comprehensive diagnostic information to the clinicians and attending physicians quickly. The final results of the examination will be available to you referring physician within a couple of hours.

What happens during the scan?

As mentioned above, you will be given an injection of a radiopharmaceutical and requested to relax in a quiet area while the injection circulates. This period lasts from 45 to 90 minutes, depending on the specific exam requested.

When it is time for your scan, you will be asked to lie on the patient table, which moves through the biograph machine. You may be asked to hold your breath periodically, especially if the chest area is being scanned. This will prevent chest movement which may blur the images, just like it would in a photograph. The CT portion of the machine may make some whirring and clicking noises. The only thing expected from you during the scan, is to lie quietly and be as still as you can.

Are there any risks associated with this scan?

The exposure to small amounts of radiation for a Medical Imaging study is the most common risk associated with a PET/CT examination. Other risks are attributed to the contrast medium which might be used for the CT portion of the scan. There are a small number of people who are allergic to this material. Please discuss any allergic history at the time of the exam, with the nurse or technologist. Be sure to talk with your referring doctor about any potential risks associated with your scan.

How will this scan help me?

PET and CT are both recognized as valuable diagnostic tools in their own right, but in the case of the biograph, the sum of these two technologies is greater than the individual parts. CT (Computed Tomography) creates images with extreme anatomical detail. However, CT does not show the living processes taking place in the body. PET (Positron Emission Tomography) images reveal much about the living processes in the body, but lack the detail to pinpoint the exact location which these processes are taking place.

That’s where Biograph comes in. A PET scan may reveal the existence of a tumor, but not it’s precise location in the tissue. The Biograph image, with it’s anatomical detail, allows the physician to detect the tumor and know it’s exact location. The benefits to the patient are multiple - earlier diagnosis, accurate staging and localization, precise treatment and precise patient monitoring. It may interest you to know that Biograph was selected by TIME magazine as one of it’s Inventions of the Year for 2000.
